A complete Dyson swarm placed just beyond Earth’s orbit would dramatically alter the balance of solar radiation, pushing Earth’s global average temperature up by 140 K.

A new paper explores this and concludes that a complete Dyson swarm outside the orbit of Earth would raise our temperature by 140 K. The concept of a Dyson swarm is purely a hypothetical concept ...

As a consequence, sci-fi writers and astrophysicists have considered partial shell pieces or a patchwork surrounding a star as a realistic Dyson sphere. Similarly, a rigid ring around a star or ...
